You may know the saying: An apple a day keeps the doctors away. A recent study by the Chinese University of Hong Kong has discovered another saying: An apple a day keeps old age away.

The study involved fruit flies, as they share many genes with humans. Researchers gave one group of fruit flies normal food, and another group of fruit flies got the same food including apple.

The results showed that flies that ate apple lived an average of 55 days longer than the flies that didn’t eat apple. The study also found that apple-eating flies were more able to walk, climb and move about as they became old, the Journal of Agricultural and Food Chemistry reports.

The researchers believe that the antioxidants (抗氧化剂) found in apples are good for health.

In another experiment, researchers studied the diets of thousands of women. They found that those women who often ate apples were 20 percent less likely to have a heart attack.

Scientists have recently discovered the apple’s genetic code. This allows scientists to make new kinds of fruit that are healthier. Researchers are already using this information to grow apples with added antioxidants. Antioxidants help to keep eyes and joints (关节) healthy and protect against heart attacks and cancer.

Apples that help people lose weight may be in supermarkets in just four or five years. They are said to be “extra healthy” apples that can stop people from overeating.

1.Fruit flies were used in the research because_______.

A. they are very easy to catch B. they are fond of eating apples

C. they can live longer than before D. they share similar genes with humans

2.By studying the diets of many women, researchers _______.

A. found they are healthier than men

B. helped them lose weight successfully

C. discovered the genetic code of the apple

D. proved apples were good for people’s health

3.From the story, we can infer that _____.

A. scientists are studying new types of apples

B. apples’ genetic code is similar to other fruits

C. women like to eat apples more often than men

D. people who eat apples are protected from heart disease

Love Tunnel sees lots of love and trash

Bearing a resemblance to the forest-surrounded “Love Tunnel” in Ukraine, the two?kilometer tunnel in Jiangning district Nanjing saw a recent rise in popularity as more than 2,000 tourists paid a visit every day this summer.The high number of visitors caused traffic safety concerns and increased the workload of sanitation workers.The Nanjing government had intended to cut the trees by the end of 2014.After the Nanjing government was forced to draft plans to cut the trees due to public pressure, visitors poured into a railway section that runs through thick forest for sightseeing and to take photos this weekend, leaving the railway with overwhelming piles of trash.

However, in response to the government's plan, complaints and outcries were made by the citizens that the love tunnel should be reserved.They claim that walking along the leafy green tunnel is like entering a fairy tale, and a possible decision to tear down the trees could bring the story to a pitiful end.

Passage 1

Passage 2

The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun,while providing safer driving conditions along with power. American inventors of the Solar Road said that it will power itself,and reduce the country's carbon marks. Many panels are fixed on the Solar Road. The top of the Solar Road panels is made of glass and the inventors are working together with top glass researchers to develop super?strong glass that would offer vehicles pulling power they need. The Solar Roadway creates and carries clean renewable electricity and, therefore, electric vehicles can be recharged at any rest stop,or at any business that uses solar road panels in their parking lots.

How to Say No to Your Boss

Saying “no” to a request can be a difficult thing, especially when the person making the request is your boss.1.The following steps are helpful.

Give yourself some time to think about the request before saying “no”.

If the request arrives via email, don’t reply right away.

2.If your boss asks you in person or on the telephone, request some time to give it thought and tell her you will get back to her by a specific time. Consider the request carefully to determine whether you have to say “no”.

Prepare your answer before telling your boss “no”.

Anticipate questions she might ask in response to your answer, and decide how you want to answer them. Rehearse your conversation with your boss out loud to help build your confidence before the real conversation.

Choose the right time and place to speak with your boss.

Have the conversation in private if your work situation allows you to get a moment alone with your boss. Keep in mind your boss’s workday pressures and work style. If she is a morning person and gets grumpy(脾气暴躁的)in the afternoon, be sure to speak with her before lunch.

3.

If your boss is asking you to take on more responsibility, that shows that she has faith in your ability to do the job. Acknowledge that it means a lot to you before telling her that you feel you cannot do it.

Tell your boss why you have to say “no” to the request.

4.Your boss will be grateful that you answered honestly, rather than trying to take on a project you cannot handle.

Offer an alternative solution.

For example, if your boss asks you to serve on a committee, suggest someone else in the company that you think may be interested and capable of serving.5.

A. Pay your boss a compliment while denying her request.
